[Bug 599255] Re: dmraid fails to read promise RAID sector count larger than 32-bits

[TJ]

Ghah! After pressing "Post Comment" also found this firmer confirmation
of (part of) the algorithm:

"Solution: From 0-2 TB the sector size is 512k. From 2-4 TB the sector
size is 1028k. Then from 4 + it changes the sector size to 2048k thats
why the information is displayed in as unallocated. Following this
parameters when expanding should make expanding the array work."
